Sending mail from different address using Mail.app

[laytonhayes]

I have 4 different email addresses that are forwarded to my .Mac mail address. Whenever I send out an email it is always sent from my .Mac mail account. I would like to send mail using my .Mac IMAP server (because it stores them on the server) but have the address appear it came from one of my forwarded emails. Possible or anything similar? Thanks.

I don't have .Mac, but I think the problem you're referring to is the same as the one in this thread (http://forums.macrumors.com/showthread.php?t=112689&highlight=mail.app+.mac+addresses), so please take a look and see if it helps?
